Canadians face flight delays as US lifts nationwide ground stop
Canadians experienced widespread flight delays and cancellations after US authorities lifted an unprecedented nationwide ground stop triggered by an air traffic control communications outage.
Canadians faced lingering flight delays after US aviation authorities lifted an unprecedented nationwide ground stop that halted air travel across the United States. According to reporting compiled by the Times Colonist, airports across Canada suspended flights to and from the US, while Air Canada cancelled all remaining U.S.-bound flights for the rest of the day.
The disruption unfolded after the Federal Aviation Administration (FAA) issued a countrywide ground stop on Friday afternoon, citing extraordinary circumstances and safety concerns stemming from severe communications problems at regional air traffic control centres. Transatlantic schedules were similarly upended, as noted by the Express, while the Twin Cities reported that the shutdown marked the first nationwide grounding of flights in the United States since January 2023, and the first of this scale outside of the September 11, 2001, attacks.
Media additions
U.S. Transportation Secretary Sean Duffy and U.S. Homeland Security Secretary Markwayne Mullin addressed reporters, explaining that the nationwide disruption was tied to a telecommunications outage and data-overloaded routers within the air traffic control system. Secretary Mullin stated that there was no indication the communications failure was related to a cyberattack or a terrorist threat. Officials noted that the system relies on aging infrastructure and analog equipment.
Canadian officials mobilized in response to the crisis. Transport Minister Steven MacKinnon issued a media statement confirming that Nav Canada measures helped safely manage traffic volumes and reassured the public that Canadian air traffic management systems continued to function normally. Minister MacKinnon also announced that Canada offered its full assistance to the FAA, including the accommodation of U.S.-bound aircraft as required. At Toronto Pearson International Airport, international and domestic flights continued to operate where routes did not require transit through U.S. Airspace, while support teams were deployed to assist affected passengers and implement aircraft parking plans.
Domestic impacts within North America were severe, stranding numerous collegiate and professional sports teams. As detailed by the Twin Cities, athletic programs including the NBA's Brooklyn Nets—who were halted on the tarmac in New Orleans—along with college football squads such as Utah, Texas, Tennessee, and Ole Miss, were left stranded or forced to pivot to charter buses.
| Airline / Airport / Agency | Reported Impact |
|---|---|
| Air Canada | Cancelled all remaining flights to and from the US for Friday evening |
| Eurocontrol | Suspended all flights departing European member countries bound for US airports |
| Toronto Pearson International Airport | Continued operating non-US transit routes while increasing terminal staffing and implementing aircraft parking plans |
| Nav Canada | Maintained normal civil navigation operations while monitoring the situation and managing traffic volumes |
International coordination bodies also reacted swiftly to the emergency. Eurocontrol suspended all flights departing from the European Civil Aviation Conference area bound for US airports following a request from the FAA. Meanwhile, carriers adjusted regional networks; Alaska Airlines reported that flights within Alaska and neighbor island flights in Hawaii were unaffected, and flights from the West Coast to Hawaii were cleared to continue.
While the FAA lifted the ground stop later on Friday evening after testing system stability, officials warned that recovery would be slow. Passengers have been advised to check flight statuses directly with airlines, as residual delays, gate congestion, and scheduling adjustments are expected to persist.
What to watch next
- Airlines working through backlogs and repositioning stranded crews and aircraft.
- Congressional debates over emergency funding requests for national airspace modernization.
